Whether your Blackberry Bold 9780 not accepting other network sim card?It is because of network lock.Without unlocking you cannot use other network sim card in it.To unlock it you can use unlock code.Get the unlock code from the site Unbblock.com and unlock it from any GSM network sim card.You cannot use CDMA network sim card in it.Check unlock code is available for your network and country,if it is available get it and unlock it.Then use any GSM network sim card.It won't display invalid sim or ask for an unlock code.Good Luck.
